Scientists examined for life deepest basin crust on the bottom of the Caribbean Sea. According to NASA, the possibility of life on such incredible depths and under such extreme conditions may be indicative of its extraterrestrial origin.
Established NASA research team found three hydrothermal vents, which are cracks in the surface of the earth,
of which the hot geothermal water. One is particularly struck by the scientists mouth extends 5 km under the sea and 100 kilometers along.
He was named the Central Cayman Rise (Mid-Cayman Rise). This area of the seabed is an ultra-slow expanding range, which is part of the tectonic boundary between the North American and Caribbean plate.
Despite the fact that geothermal vents away from sunlight and are under extreme pressure from the ocean, some of them are hot as convection ovens. But, nevertheless, scientists discovered that vents are home to hundreds of mikroogrganizmov. This finding may provide a clue about how life exists on other planets.
"Most of life on earth formed around food chains and fueled solnenchym light as a necessary source of energy. But this is not a necessary condition for the existence of life deep in the ocean icy moons of Jupiter — Europe, the study of which is the supremacy for NASA. "
Organisms living near deep sea vents are arranged quite differently and are powered chemicals hydrothermal vents. Scientists believe that the same principle microorganisms exist on the moon of Jupiter — Europe. In their view, this work will help to understand how the structure of extraterrestrial life.
Research team were published in a scientific journal.
Chris Herman — head of the team of researchers, scientist and geochemist, Institute of Oceanography, Woods Hole, said the team is trying to apply this knowledge to future plans for space exploration. The work done can be a tool to search for life on Mars and moons with ice oceans.
One of the scientists detected trough name Pickard, he is 780 meters deeper than previously known trough found in the Pacific Ocean in 1977.
Another trough — Walsh, was found in the rocks, which are composed of a material similar to lava, they could appear on the bottom of the ocean thousands of years ago during the formation of the bottom.
The third site — Europe — named after the ice moons of Jupiter, scientists say contains life.
Vents have been studied by the research team of unmanned robots, programmed to track chemicals and germs emitted runners.
The researchers say that the mission for the first time will provide information about microorganisms that can exist in great depth in the absence of oxygen. Herman pologayu that his team has gone so far that I could find a community of organisms that exist due to the chemical energy sources.
The team plans to resume work with vents to learn more about life there. Herman also said that the team wants to take an exploratory mission to Artik, where conditions are more organisms are close to those that are on other planets.
